Hmm, but every nonzero integer DOES have a multiplicative inverse - that value isn't another integer, but there is one. If the floating point value 2.0 has a multiplicative inverse 0.5, doesn't the integer value 2 also have that same multiplicative inverse? Your definitions are rather odd in places here. I'm not saying they're wrong, but I can't disprove the things you're saying are impossible, so it's hard for my brain to grok it.
